rmdev 删除之后 cfgmgr就又出现了。

系统中报磁盘操作错误

解决方法一：

进入Navisphere，点击Storage Groups -> 选择你出现鬼盘的Group -> Hosts ->选择出现鬼盘的host -> 点击鼠标右键 ->  Connectivity Status

-> 是不是会看到一个“~management”组

如果看到，选择WWN地址，然后点击reconnect按钮，会把这个WWN地址注册到你选择的Group里。

然后再运行下列步骤删除鬼盘：

powermt remove dev=all
lsdev -Ct power -F name | xargs -n1 rmdev -dl
lsdev -Ct CLAR_* -F name | xargs -n1 rmdev -dl
/usr/lpp/EMC/CLARiiON/bin/emc_cfgmgr
powermt config

处理“~management”组，方法二（待验证，慎用）：

go to storage group properties, host tap, enter enginneerit mode (CNTRL+SIFT+F12 ..password "messner"), You will see "Advanced botton". Select it and then look at your host, if there are paths that are not selected go ahead and select them and hit OK.
